Where do we get all of this knowledge about keyword demand and keyword referrals? From research sources like these:

Wordtracker’s Free Basic Keyword Demand

We at Webcraft custom-built the Keyword Explorer tool from the ground up to help streamline and improve how you discover and prioritize keywords. Keyword Explorer provides accurate monthly search volume data, an idea of how difficult it will be to rank for your keyword, estimated click-through rate, and a score representing your potential to rank. It also suggests related keywords for you to research. Because it cuts out a great deal of manual work and is free to try, we recommend starting there.

Google’s AdWords Keyword Planner tool is another common starting point for SEO keyword research. It not only suggests keywords and provides estimated search volume, but also predicts the cost of running paid campaigns for these terms. To determine volume for a particular keyword, be sure to set the Match Type to [Exact] and look under Local Monthly Searches. Remember that these represent total searches. Depending on your ranking and click-through rate, the actual number of visitors you achieve for these keywords will usually be much lower.

Other sources for keyword information exist, as do tools with more advanced data. The Webcraft blog category on Keyword Research is an excellent place to start. If you’re looking for more hands-on instruction, you can also check out Webcraft premium Keyword Research Workshop.
